Hello, I've recently purchased a 91 300e with 185000 miles on it . The car is clean and was well maintained with records to prove it. Having said this, there is no record of and trans or rear fluid change and there is a oil leak somewhere under the front end. I plan on steaming the engine and looking for the leak but is there anything else that I should be taking care of or looking for from a mechanical standpoint and what kind of overall milage can I expect. The only cosmetic problem is the interior wood panel on the shift console which is cracking. Thanl you!
